The Azimuth Project
Blog articles in progress (Rev #30)

Contents

There are usually several blog articles in various states of progress that need feedback and are being actively discussed in the forum before being posted to the blog. You can find them here.

Azimuth Project news

Summary: What’s new on the Azimuth Project?

Curtis Faith on the Azimuth Project

Summary: Curtis Faith introduces himself and talks about why he decided to help out on the Azimuth Project.

Making decisions under uncertainty

Summary: Groups often want to make the right decisions. So they spend a lot of time in the decision process itself. A better approach is to acknowledge when perfect decisions don’t exist and to incorporate the uncertainty itself into your plans.

Week 309

Summary: Another application of Hopf bifurcations with noise, this time to predator-prey systems.

Network theory (part 1)

Summary: Networks, and diagrams of networks, show up in many branches of science. It would be nice to find a unified framework for these ideas.

Network theory (part 2)

Summary: One can adapt ideas from quantum field theory to describe the theory of stochastic Petri nets. The master equation versus the rate equation.

Network theory (part 3)

Summary: The rate equation of a stochastic Petri net, and applications to chemistry and infectious disease.

Network theory (part 4)

Summary: The master equation of a stochastic Petri net, and analogies to quantum field theory.

Network theory (Biamonte guest posts)

Summary: stuff by Jacob Biamonte about stochastic Petri nets and chemical reaction networks, which might go into posts on the Azimuth blog.

Network theory (part 5)

Summary: Analogies between quantum theory and probability theory.

Network theory (part 6)

Summary: Writing the master equation using annihilation and creation operators.

Network theory (part 7)

Summary: An example: the stochastic version of the logistic equation in terms of annihilation and creation operators, and how to obtain an equilibrium Poisson distribution.

Stabilization wedges (part 5)

Summary: Pacala’s 2008 followup on the original Pacala-Socolow Stabilization wedges paper.

Peak oil

Is My Climate Model Right? A Software Engineering Perspective

Summary: Critics of climate science in general, and sceptics of the statement that anthropogenic (man-made) global warming is real, often claim that climate models are wrong and cannot be trusted. But what does “wrong” mean here and what can and should be done to make models more trustworthy, from a software engineering viewpoint? In a first step, we’ll introduce some relevant technobabble.

Week 314

Summary: The first part of an interview with Thomas Fischbacher.

Putting Earth Into a Box

In introduction to energy balance models.

Summary: An introduction to energy balance models.

A Quantum of Warmth

Summary: An explanation of downward longwave radiation (DLR), generated by the atmosphere of the earth. Why it does not violate the second law of thermodynamics and what measurements say.
